Update (06/20):
- Improved its installer so that the message like “This program might not have installed correctly” won't be shown on Windows 7/8.
- Added Hungarian Language support.
- Supported 3 more languages in partial.

Due to Microsoft's decision, the priviledge levels of the Explorer and the drop source/destination programs have to be exactly the same for any drop operations to work. If the Explorer is running under the Administrator's priviledge, please excute our program in the Administrator's priviledge also.

Also, if you want to drop system protected files onto the drop box, you may have to run both Explorer and our program in the Administrator's priviledge. Otherwise, you may change the file attributes to non-system protected ones or move them to non-system protected folders before you drop them onto the program.

We've been looking for any solution to hack this issue around. However, please understand it's exactly the planned behaiver by Microsoft.
